Abstract

The invention belongs to the field of composites, and discloses a high-glass / mineral-fiber-content high-gloss polyamide material and a preparing raw material, preparing method and application thereof.The preparing method of the high-glass / mineral-fiber-content high-gloss polyamide material includes the steps of S1, evenly mixing a hydrogen bond inhibitor with an optional lubricant and antioxidantin advance to obtain a powdery material package, and evenly mixing semi-crystalline polyamide, amorphous polyamide and the powdery material package to obtain a main material; S2, weighing the main material through a weightlessness scale and feeding the main material from a main feed port of a twin-screw extruder, weighing glass / mineral fiber through the weightlessness scale and feeding the glass / mineral fiber from a side feed port of the twin-screw extruder, and conducting melting and extruding, rinsing and cooling, and pelletizing on all the materials in the twin-screw extruder to obtain thehigh-glass / mineral-fiber-content high-gloss polyamide material. The polyamide material obtained through the method has high mechanical strength and high glossiness and is quite suitable for preparingshell type structural parts with high requirement for glossiness and visual sensory effect.

Description

technical field

[0001] The invention belongs to the field of composite materials, and in particular relates to a high-gloss polyamide material with high glass mineral fiber content and its preparation raw material, preparation method and application. Background technique

[0002] Polyamide (nylon, PA) is an engineering plastic with excellent comprehensive properties. Nylon has high mechanical strength, heat resistance, abrasion resistance, chemical resistance and electrical insulation. Nylon materials are widely used in the automotive industry, electrical and electronic industries, transportation, machinery, aerospace and other fields. High-gloss nylon can obtain excellent appearance effects of products through direct injection molding, such as high-gloss and metallic effects. Nylon base material can be modified to obtain high mechanical strength and high gloss effect, which can replace some metal parts, toy parts and household kitchen and bathroom parts and other shell pr...
